Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in Panama

Background

In the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems.

Tree Management in the Northwestern Andean Cordillera of Peru

Background

Peasant communities in the northwestern Andean Cordillera of Peru utilize many indigenous and introduced trees and shrubs to satisfy a variety of material needs. However, forest resources are over-harvested and over-grazed, contributing to soil erosion. This study aims to identify the major tree and shrub species in the region and understand their ecologies and usages, and to recommend priorities for reforestation in the region taking human usage into account.

Reforestation of Abandoned Pastures: Silvicultural Means to Accelerate Forest Recovery and Biodiversity

Background

Despite the 2736 native tree species in Ecuador, the majority of forestation activities in the country are based on exotic pines and eucalypts. In this book chapter, the authors describe the reason for this neglect being the lack of knowledge on the ecology and silvicultural treatment and the lack of nurseries growing these species.

The Agua Salud Project, Central Panama

Background

The Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region.

Woody Understory Plant Diversity in Pure and Mixed Native Tree Plantations at La Selva Biological Station, Costa Rica

Background

This study compares the species richness, abundance, and seed disperal method of individuals growing in the understory of native single-species plantations, native mixed-species plantations, and naturally regenerating (non-planted) areas of the La Selva biological station in Costa Rica.

Native Trees and Shrubs for the Productive Rehabilitation of Tropical Cattleranching Lands

background

The authors of this study examined strategies to improve cattle ranching in Colombia and Mexico through the use of intensive silvopastoral systems. Silvopastoral systems transform extensive cattle ranching with intensively managed systems with high densities of trees and shrubs to improve yields and environmental impacts.

Studies on the Seed Biology of 100 Native Species of Trees in a Seasonal Moist Tropical Forest, Panama, Central America

Background

Since 1998, the Panama Canal Watershed has experienced a decline in forest cover. The watershed ensures a functioning canal, thus there has been a significant investment in resources to reforest and restore the region. While these projects have focused primarily on native species, there has been issues with seed-handling.
